Guest Jef Posted May 1, 2008 Posted May 1, 2008 after installing SP2 on a domain controller i have random computers on the domain that are getting a "Logon Failure: Target account name is incorrect". when i look in the event viewer i also see a kerberos error event id 4 and the user cannot access any network resources. If we wait 5 minutes and then restart the users computer everything works fine. The only thing i have done to the server is installed SP2, what could be the problem?

Well, you have some catching up to do in terms of info. SP2, whether you like it or not, puts the SNP (Scalable Networking Pack) in there for you and has features enabled by default. A lot of people have had problems because SNP. Be aware of the following two KB articles regarding post-SP2 issues: http://support.microsoft.com/kb/945977 http://support.microsoft.com/kb/939421 Next, ensure you have the *latest* NIC driver. This can often resolve some things. SP2 and the SNP require drivers that are Network Driver Interface Specification (NDIS) 5.2 complaint or higher. I would then suggest getting this KB update to turn off the SNP junk: http://support.microsoft.com/kb/948496 See if the NIC driver and the update from 948496 help. Let know how it goes. - Thee Chicago Wolf
